I have an obx header, I think the flex pipe was leaking right out of the box. And I have seen a subaru on google that had peices inside the catalytic convertor. Is obx always that shotty?

 

I had an OBX header and the flanges where the 2 pieces meet warped within a year. OBX = ****

 

yeah OBX is pretty bad, i bought a T304 stainless header for like 55shipped the other day

t304 is shitty *** stainless-lots of carbon, fairly brittle
also in the pic, the collector O2 hole is after the flex pipe....tards

 

had the same problem with obx header on the stock motor, reason is its a single wall flew pipe. You can cut it out and upgrade to a double wall flew pipe. visit your local exhaust shop they can take care of it for you.
